KEBA PLCs use a PCIe FPGA to implement several functions in a common way. This is a first step to include basic support for this FPGA. Under drivers/misc the cp500 PCI driver is added. This drivers creates auxiliary devices for every function inside the FPGA. As a first step it only creates auxiliary devices for the I2C controllers. The I2C controller driver is added under drivers/i2c/busses like all the other I2C controller drivers. This patches enable access to the EEPROMs and to the hardware monitoring chip of KEBA PLCs. v5: - simplify (ret != 0) (Andi Shyti) - change KI2C_RECOVERY_CLK_CNT to (9 * 2) (Andi Shyti) - change KI2C_RECOVERY_NDELAY to KI2C_RECOVERY_UDELAY (Andi Shyti) - rework reset while loop to for loop (Andi Shyti) - use dev_err() for errors (Andi Shyti) - don't define int i within for loop (Andi Shyti) - use else if within read loop (Andi Shyti) - remove unnecessary parenthesis of (ret < 0) ? ...

Hello Andi, are there any reasons why this patch does not make any progress? Did I miss something? Or is it hanging just because of holiday season? Thanks, Gerhard
